Film noir Nightmare Alley is released next week. It's director Guillermo del Toro's remake of the 1947 film - a baroque tale of carnival hucksters, psychiatrists and betrayal.

Ellen E Jones and Mark Kermode explore the connections sparked by Nightmare Alley and film noir.

Mark speaks to Guillermo del Toro about his five favourite classic noir films, including Fallen Angel and Born to Kill.

And Ellen looks at how neo-noir movies subverted and reframed the genre from the 1970s onwards, with the help of critics Imogen Sara Smith and Amon Warmann.
